No because adding the two fives will give you a 10 and 10 is greater than 3
You take the orignal price of the video game and subtract the new price to see how much it was reduced. 60-45 = 15. then you take the reduced amount of the game (15) and divide by the original price (60).
you get 25%
your answer is B
Y = 48 becuase you travelled the amount of minuets 45 x
Answer:
.
Step-by-step explanation:
Given homogeneous equation
![x^2ydy+xy^2dx=0](https://tex.z-dn.net/?f=%20x%5E2ydy%2Bxy%5E2dx%3D0)
![\frac{\mathrm{d}y}{\mathrm{d}x}=-\frac{xy^2}{x^2y}](https://tex.z-dn.net/?f=%5Cfrac%7B%5Cmathrm%7Bd%7Dy%7D%7B%5Cmathrm%7Bd%7Dx%7D%3D-%5Cfrac%7Bxy%5E2%7D%7Bx%5E2y%7D)
Substitute y=ux , ![u=\frac{y}{x}](https://tex.z-dn.net/?f=u%3D%5Cfrac%7By%7D%7Bx%7D)
![\frac{\mathrm{d}y}{\mathrm{d}x}=-\frac{y}{x}](https://tex.z-dn.net/?f=%20%5Cfrac%7B%5Cmathrm%7Bd%7Dy%7D%7B%5Cmathrm%7Bd%7Dx%7D%3D-%5Cfrac%7By%7D%7Bx%7D)
Now,
![u+x\frac{\mathrm{d}u}{\mathrm{d}x}=\frac{\mathrm{d}y}{\mathrm{d}x}](https://tex.z-dn.net/?f=u%2Bx%5Cfrac%7B%5Cmathrm%7Bd%7Du%7D%7B%5Cmathrm%7Bd%7Dx%7D%3D%5Cfrac%7B%5Cmathrm%7Bd%7Dy%7D%7B%5Cmathrm%7Bd%7Dx%7D)
![u+x\frac{\mathrm{d}u}{\mathrm{d}x}=-u](https://tex.z-dn.net/?f=u%2Bx%5Cfrac%7B%5Cmathrm%7Bd%7Du%7D%7B%5Cmathrm%7Bd%7Dx%7D%3D-u)
![\frac{\mathrm{d}u}{\mathrm{d}x}=-2u](https://tex.z-dn.net/?f=%5Cfrac%7B%5Cmathrm%7Bd%7Du%7D%7B%5Cmathrm%7Bd%7Dx%7D%3D-2u)
![\frac{du}{u}=-\frac{dx}{x}](https://tex.z-dn.net/?f=%5Cfrac%7Bdu%7D%7Bu%7D%3D-%5Cfrac%7Bdx%7D%7Bx%7D)
Integrating both side we get
lnu=-2lnx+lnC
Where lnC= integration constant
![lnu+ln{x}^2=lnC](https://tex.z-dn.net/?f=lnu%2Bln%7Bx%7D%5E2%3DlnC)
![lnux^2=lnC](https://tex.z-dn.net/?f=lnux%5E2%3DlnC)
Cancel ln on both side
![ux^2=C](https://tex.z-dn.net/?f=ux%5E2%3DC)
Substitute ![u=\frac{y}{x}](https://tex.z-dn.net/?f=u%3D%5Cfrac%7By%7D%7Bx%7D)
Then we get
xy=C
